View and Delegate and Menu

hey,

the menu2 sample of the SDK has this stupid intro....I tried to skip that...but maybe need to know more about the view and delegate menu class stuff....in JS for example there is this "historyobject for views"....how are backs handled...in delegate it is clear...but the example has nothing about this back in view class.-..or how is that working in a menu class.....I tried the back stuff in this classes, but on real device, that didn t work...I m just doing it for a hobby....any hints?
